As outlined by a psychology professor Julijan Holt-Lanstad:"A relationship helps us fight with stress. A partner guarantees emotional support. Likewise, people who are in a relationship pay more attention to training and proper nutrition..."

Arthur Aron a psychologist at New York University scanned the brains of people who are in different stages of love, to understand the mechanism of the influence of emotions on human health and he found out that: love leads to the release of dopamine in the brain. Dopamine is a neurotransmitter that affects pleasure and motivation. The same effect is obtained when a person gets a lot of money or takes cocaine.
Specifically Aaron compared the results of the scan from 17 persons, who were on average 21 years of marriage, with the results of the 17 people who had recently fallen in love. In all patients, was observed activation of dopamine in the brain, but at the brain of lovers who were not married zones that are responsible for anxiety stress and obsession were shining.

Simply just holding hands and hugging provokes the release of the hormone oxytocin, which reduces the level of stress hormones, lowers blood pressure, improves mood and reduces sensitivity to pain, according to a research made at the University of North Carolina. And researchers at the University of Ohio had previously found that the feeling of love helps heal wounds faster.

For people who have not yet fallen in love Julijan Holt-Lanstad aspires: the existence of strong ties with friends and relatives compensates the lack of romantic relationships,increasing the chances of survival by 50%.If a person gets divorced,he may begin to suffer more,because divorce has bad effect on our health.
